The Q-Lab Q-SUN Xe-3-HDSBSCE Flat-Array Xenon Arc Test Chamber with RH, Dual Spray, Back Spray and Chiller is an advanced full-size xenon arc weathering tester for laboratories that need controlled sunlight, heat, humidity, complex spray exposure and lower chamber air temperature capability. This extended Xe-3 Model E configuration combines relative humidity control, dual spray, front/back spray and a chiller in Q-Lab’s flat-array Xe-3 platform. It is designed for technical buyers testing coatings, plastics, automotive materials, textiles, packaging, sealants, printed materials and selected product components where degradation is driven by light, temperature, humidity and advanced wetting cycles. For laboratories comparing Q-SUN Xe-3 configurations, the Xe-3-HDSBSCE is the most feature-rich extended configuration in this group, adding chiller capability to the dual spray and back spray platform.
Test Standards Supported
The Q-SUN Xe-3-HDSBSCE supports xenon arc weathering and lightfastness methods where the selected cycle requires irradiance, chamber air temperature, black panel or insulated black panel temperature, relative humidity, spray capability and lower chamber air temperature operation. Exact suitability depends on the selected optical filter, irradiance control point, temperature setpoint, RH setpoint, spray cycle and test fluid requirements.

Specimen Capacity and Configuration
The Q-SUN Xe-3-HDSBSCE uses a large flat-array specimen tray with a 45 x 72 cm exposure area and capacity for 55 specimens at 51 x 102 mm. The near-horizontal 10° specimen orientation is useful for testing flat panels, coated coupons, plastics, textiles, packaging samples and selected three-dimensional parts. Q-Lab notes that Xe-1 and Xe-3 specimen capacities are listed without specimen holders, so holder selection should be confirmed during configuration.
The key configuration advantage of Xe-3-HDSBSCE is its combination of dual spray, back spray and chiller capability. Dual spray supports a second spray liquid, back spray allows wetting on both sides of specimens, and the chiller supports lower chamber air temperature operation. This makes the model suitable for advanced weathering programmes where simple light, heat, humidity and front spray exposure is not enough to match the required service environment or customer method.
Operating Specifications
The Xe-3-HDSBSCE is an S model, so it requires high-purity water. Q-Lab lists the water requirement for all S or W models as inlet pressure of 2.1 to 6.2 bar, resistivity greater than 5 MΩ.cm, conductivity less than 0.2 μS/cm, total dissolved solids less than 0.1 ppm and colloidal silica less than 0.1 ppm. Q-Lab also recommends pH 6 to 8 and use of a reverse osmosis/deionisation system for best performance.
For facility planning, the main Xe-3 chamber external dimensions are 91 x 178 x 99 cm, and the chiller dimensions are 78 x 94 x 94 cm. The dual spray system includes a separate reservoir and pump enclosure, so additional floor space should be allowed for the full installation. The rear Xe-3 vent duct can be removed to reduce chamber depth from 99 cm to 88 cm for movement through small doors.
The electrical requirement for Xe-3-HDSBSCE is 208 V or 230 V, 3-phase at 44 A, or 400 V, 3-phase at 26 A, with voltage tolerance of plus or minus 10% and 50/60 Hz operation. The recommended laboratory ambient condition is 23 ± 5 °C and 50 ± 25% relative humidity. Q-Lab states that operation outside these conditions can cause temperature, humidity or other faults, and the chamber should not be operated above 36 °C ambient or above 80% RH.
Why Choose the Q-Lab Q-SUN Xe-3-HDSBSCE?
The Q-Lab Q-SUN Xe-3-HDSBSCE is suited to laboratories that need the most advanced moisture and temperature capability in the Xe-3 flat-array family. Compared with Xe-3-HDSBSE, it adds chiller-supported lower temperature operation. Compared with Xe-3-HSCE, it adds dual spray and back spray. Compared with Xe-3-HBSE, it adds both dual spray and chiller capability. This makes it a strong configuration for demanding R and D, automotive, coatings, plastics and customer-specific durability programmes.
For technical buyers, the main commercial value is capability consolidation. The Xe-3-HDSBSCE combines three air-cooled xenon lamps, SOLAR EYE irradiance control, humidity control, BP or IBP plus CAT control, dual spray, back spray, chiller operation, AUTOCAL calibration and a large flat specimen tray. This supports repeatable, documented accelerated weathering and lightfastness testing where multiple environmental stressors must be controlled in a single chamber.
